To @ZZ whom it may concern,.- l

Be it known that l, MORRIS B. HALL, of Essex, in the county of Middlesex and State of Connecticut, have invented a certain new and useful Improvement Pertaining to Windowl-Ioists, of which the following is a description, reference being had to the accompanying drawings, where- Figure l is a front View of, my device attached to a window, with the swing buttoued back to the tacklerframe. Fig. 2 is a central vertical section of the same device which is shown in Fig. l, with the swing let forward and the landing-plate in place.

One main object of theimprovement herein shown and described is to aid in hoistingfrom the ground to the window of any ofthe upper stories of a building any heavy object, like a piano or safe, and the convenient conveyance of the same through the window and into the building. i

rI he letter a denotes what may appropriately be termed a tackle-frame, intended to be temporarily attached to a window, for the purpose hereinbefore specified.

The letter b denotes aledge-support projecting from the side of the lower part of thetackleframe, andintended to rest upon the lower part of the window, commonly called a win-4 dow-ledge.77

The letter c denotes-what may be termed the upper support77 of theV tackle-frame. It is pivoted to the tackle frame so that its opposite end may be vertically adjustable for the purpose of attaching the tackle-frame to windows of different heights.

The letter d denotes clamp-hooks to be temporarily affixed to the top of the window-opening, for which purpose they are provided with set-screws d', and also provided with hooks d, to take temporary hold of the upper support, c.

The letter e denotes the tackle as a whole, by which the heavy object is to be raised from the ground up t0 a point above the bottom of the window.

The letter f denotes what I will term, a swing, pivotally attached to the tackleframe, and buttoned back to the tackle-frame while the weight is being raised, as illustrated in Fig. l. After the weight is up this swing is swung forward or outward, as shown in Fig. 2, when it will be beneath the heavy ob: ject which has just been raised. A landingplank, g, is then laid from the window-ledge into the swing and the heavy obj ectis deposited thereon. The heavy burden and the landing- .plank are swung inward till the Vburden rests upon the window-ledge, when the landingplank is carefully tipped until its inner end hooks for the upper part of the window, alll substantially as described, and for the purpose set forth.
